Although anemia is a known risk factor of mortality in several patient populations, no prospective study to date has demonstrated association between anemia and mortality in kidney-transplanted patients. In our prospective cohort study (TransQol-HU Study), we tested the hypothesis that anemia is associated with mortality and graft failure (return to dialysis) in transplanted patients. Data from...
Immaturity among individuals transferred from pediatric to adult-oriented care at a young age may leave them vulnerable to higher graft failure risks than in individuals transferred older. We sought to determine the impact of age at transfer on renal allograft failure rates. We evaluated graft failure rates among 440 kidney recipients recorded in the UNOS database (1987-2007), who had been tran...
BACKGROUND Vein-graft harvesting with the use of endoscopy (endoscopic harvesting) is a technique that is widely used to reduce postoperative wound complications after coronary-artery bypass grafting (CABG), but the long-term effects on the rate of vein-graft failure and on clinical outcomes are unknown. METHODS We studied the outcomes in patients who underwent endoscopic harvesting (1753 pat...
Not long after coronary artery bypass grafting surgery was described, several reports presented follow-up angiographic data on large cohorts of patients, demonstrating that approximately one-half of saphenous vein grafts fail within 10 to 15 years of surgery and that graft failure is associated with worse clinical outcomes. Three processes are responsible for vein graft failure. Thrombosis, int...
Individual HLA mismatches may differentially impact graft survival after kidney transplantation. Therefore, there is a need for a reliable tool to define permissible HLA mismatches in kidney transplantation. We previously demonstrated that donor-derived Predicted Indirectly ReCognizable HLA Epitopes presented by recipient HLA class II (PIRCHE-II) play a role in de novo donor-specific HLA antibo...
Mortality has decreased in children with end-stage kidney disease. Decreases in mortality during dialysis and improved graft survival contributed to this improvement. However, it is unknown whether rates of death with graft function have also improved. We measured this in first transplant recipients under 21 years of age registered in the US Renal Data System. Cox models were used with a time-d...
Background The residual laxity after transtibial posterior cruciate ligament (PCL) reconstruction has been reported by several authors. The sharp angle where the graft exits the tibial tunnel, which is known as "killer turn", is believed to be the main reason. The purpose of this study was to reveal the mechanism of "killer turn" and its effect on both graft and tunnel inlet. Methods A total ...
Re-intervention on abdominal aortic aneurysm treated by endovascular aortic aneurysm repair for complications such as endoleak, graft migration, and graft failure is relatively common. However, re-do endovascular aortic aneurysm repair can be complex, as the failed graft still resides within the vessel. In addition, some re-do endovascular aortic aneurysm repairs call for an advanced custom gra...
OBJECTIVES We evaluated the influence of lipid exposure upon conduit patency in long-term follow-up after primary CABG. METHODS From a prospectively compiled database, we identified 1207 grafts (436 SV and 771 mixed arterial grafts) among 413 CABG patients with 9.4 ± 2.4 years of follow-up (range 3-13). Surveillance angiography was performed as part of a randomized trial. All available lipid ...
BACKGROUND Chronic kidney disease (CKD) is a major public health problem that may lead to end-stage renal disease (ESRD). Renal transplantation has become the treatment modality of choice for the majority of patients with ESRD. It is therefore necessary to monitor the disease progression of patients who have undergone renal transplantation. In order to monitor the disease progression, the conti...
